==下载Matrix源码==
 
−
Matrix配件相关的代码是完全开源的，统一由一个仓库进行管理：https://github.com/friendlyarm/matrix.git <br>
 
−
该仓库里不同的分支代表着Matrix配件所支持的不同开发板。<br>
 
−
* nanopi分支用于支持NanoPi；
 
−
* nanopi2分支用于支持NanoPi 2；
 
−
* tiny4412分支用于支持Tiny4412；
 
−
* raspberrypi分支用于支持RaspberryPi；

==Applications==
 +
===Connect to NanoPi M1===
 +
Refer to the following connection diagram to connect the module to the NanoPi M1:<br>
 +
[[File:Matrix-Compact_Kit_B_nanopi_m1.jpg|frameless|600px|Matrix-Compact_Kit_B_nanopi_m1]]
 +
 
 +
===Connect to NanoPi M2 / NanoPi 2 Fire===
 +
Refer to the following connection diagram to connect the module to the NanoPi M2/ NanoPi 2 Fire:<br>

==Compile & Run Test Program==
 +
Boot your ARM board with Debian and copy the matrix code:
 +
<syntaxhighlight lang="bash">
 +
$ apt-get update && apt-get install git
 +
$ git clone https://github.com/friendlyarm/matrix.git
 +
</syntaxhighlight>
 +
If your cloning is done successfully a "matrix" directory will be generated.

4 Applications

4.1 Connect to NanoPi M1

Refer to the following connection diagram to connect the module to the NanoPi M1:
Matrix-Compact_Kit_B_nanopi_m1

4.2 Connect to NanoPi M2 / NanoPi 2 Fire

Refer to the following connection diagram to connect the module to the NanoPi M2/ NanoPi 2 Fire:
Matrix-Compact_Kit_B_nanopi_m2

5 Compile & Run Test Program

Boot your ARM board with Debian and copy the matrix code: 

$ apt-get update && apt-get install git
$ git clone https://github.com/friendlyarm/matrix.git

If your cloning is done successfully a "matrix" directory will be generated.

Compile and install Matrix: 

$ cd matrix
$ make && make install

Run test program: 

$ matrix-compact_kit

Note: this module is not plug and play therefore before running the module please make sure it is connected to an ARM board.
Here is what you should observe:

LED blinking 1
LED blinking 2
Button:  1 1 1
The channel0 value is 2070
The angle is 336.3
Pwm start
Pwm stop

Run Qt program to test the TFT LCD: 

cd matrix/demo/nanopi-status
./build.sh
./run.sh /dev/fb-st7735s

The program will present the system's basic information. Here is what you expect to observe:
st7735s-status

6 Code Sample

This Matrix code sample can work with all the ARM boards mentioned in this module's wiki. The name of this code sample is "matrix-compact_kit". Here is its source code: 

int main(int argc, char ** argv)
{
    int board;
 
    if ((board = boardInit()) < 0) {
        printf("Fail to init board\n");
        return -1;
    }
    testLED(board);
    readButton();
    readADC();
    readCompass();
    testPWM(board);
    // readTemp();
    // testIR();
 
    return 0;
}
